Why can't I for once dream of unicorns or something?

My head is swimming with my heart these days. Night is no longer a comfort and refuge of late. I usually can sleep away my trouble and tears and have pleasant dreams. Nightmares rarely frequent my mind but of late they seem to want to add to my troubled mental state. I already live thru the outlandish annoying depressed thoughts every day but now my one refuge for relaxation seems to have also vanished. First the dreams of me being abducted now my mind apparently wants to kill off my friends. Last night is the most memorable for me because it is still fresh and I actually decided to start writing things down. I only hope that my mom's habit or whatever its called of dreams becoming reality does not visit me and that these are merely expressions of my subconscious trying to tell me something.

I'm sitting at home when I hear my cell phone ring. I look down to see Amanda is calling and find it quite strange but pick up. Her voice is troubled and not that confident cheerfulness that she seems to spew everywhere on her normal days. She states."Sumara somethings happened." I can hear her sobbing on the other line. I am anxious and fearful. "Raynes... dead." she sputters over the phone. I drop the phone and it seems as if her voice is magnified in the room. "I tried to help, I tried to stop them but I couldn't do anything!" she screams. I feel something unexpected. Anger. I feel as if I am changing. I grab the phone and yell back "It's your own damn, fault. You both had options and you made me dead to you." The phone breaks and pieces fly everywhere. I feel so angry I feel like I can set the world on fire. I look at my hands as they begin to elongate and nails sharpen. I'm scared now but I can still feel the anger. I run to the bathroom and watch in horror has my hair grows and grows turning white. I peel at my skin because it itches so much. It comes away in flakes. Underneath is new healthy tan skin. My eyes turn black. My teeth sharpen and grow. I become taller and taller and more toned. I grin back at the mirror no longer afraid and then it bursts and there is nothing but blackness. I wake up feeling like I have been hit by a car and my shoulder stiff with pain and head throbbing. So much for sleeping tonight.

Perhaps it is just stress. I am uncertain but the nightmares of losing loved ones and waking up to new found aches and pains need to stop. Why can't I for once dream of unicorns or something?
